Abstract

Un transductor acústico comprende una parte superior (301) y una parte inferior (302), con un primer imán permanente (303) en la parte superior (301) y un segundo imán permanente (304) en la parte inferior (302). Polos magnéticos de nombre similar del primer y segundo imanes permanentes (303, 304) quedan uno frente a otro. Una cubierta superior (306) en la parte superior (301) y una cubierta inferior (307) en la parte inferior (302) comprenden material magnético y definen un encerramiento alrededor de los imanes (303, 304). Una bobina (308) crea, bajo la influencia de una corriente eléctrica, fuerzas magnéticas dinámicas. Un espacio de separación (309) entre bordes de dicha cubierta superior (306) y cubierta inferior (307) está dirigido de manera que permite un movimiento relativo de los bordes de dicha cubierta inferior (307) y dicha cubierta superior (306) entre diferentes posiciones, donde dichas posiciones difieren en la medida en que coinciden los bordes de dicha cubierta superior (306) y cubierta inferior (307).
